The invention discloses a side wall trolley which comprises a plurality of side wall trolley units spliced lengthways, wherein each side wall trolley unit comprises a trolley moving and fixing system and a steel moulding plate connecting and positioning system. The side wall trolley adopts the design of cantilever connection of a steel moulding plate and a trolley, combines hydraulic jacks, screw jacks and walking systems to realize three-position accurate adjustment, realizes bearing and transmission of load through components such as opposite supporting pipe fittings, lateral screw rod jacks, bearing jacks, tail margin guy cables and anti-floating screw rod jacks, and is stable and reliable in structure. Through the adoption of the side wall trolley, construction of a steel pipe bracket and assembly of moulding plates are not need, thus greatly simplifying construction procedures, improving the mounting speed and reliability of the moulding plates and the construction efficiency, meanwhile reducing labor in
